Hi Gary, I found a similar zfs upgrade failure with the device busy error, which I believe was caused by a file system mounted under another file system.
If this is the cause, I will file a bug or find an existing one. The workaround is to unmount the nested file systems and upgrade them individually, like this: # zfs upgrade space/direct # zfs upgrade space/dcc Thanks, Cindy On 07/29/10 09:48, Cindy Swearingen wrote:
Hi Gary, This should just work without having to do anything. Looks like a bug but I haven't seen this problem before. Anything unusual about the mount points for the file systems identified below?

This is on a Solaris 10 5/09 system._______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
